How Do You Apply Rustoleum on a Truck Bed?

Rust-Oleum is a popular brand of paint used for a variety of projects, including truck beds. The paint is designed to withstand extreme temperatures and weather conditions, making it an excellent choice for the bed of your truck. Before you begin painting your truck bed, there are some important steps you must take to ensure a smooth finish and long-lasting results.

Step 1: Clean the Truck Bed

Before applying any paint, it’s important to thoroughly clean the surface of the truck bed.

This will help the Rust-Oleum to adhere better and last longer. Start by removing any dirt or debris from the surface with a brush or vacuum cleaner. Next, use a degreaser to remove any oil or grease buildup from the surface. Finally, use a pressure washer to give your truck bed one final clean before painting.

Step 2: Sanding and Priming

Once your truck bed is completely clean and dry, it’s time to start sanding and priming. Use sandpaper to rough up the surface of the bed, removing any imperfections or rust spots that may be present. After sanding is complete, apply two coats of Rust-Oleum primer in order to create an even base coat for your paint job.

Step 3: Apply Rust-Oleum Paint

Now that you have prepared your truck bed for painting, you can begin applying Rust-Oleum directly onto it. Start by shaking up the can of Rust-Oleum before use in order to ensure even color distribution throughout your project area. Using a roller or brush, apply one even coat starting from one end of the bed and working towards the other end.

Step 4: Add Additional Coats

After you have applied one coat of Rust-Oleum paint onto your truck bed, let it dry completely before adding additional coats as desired. Depending on how much coverage you want on your truck bed and how thickly you applied each coat, you may need two or three additional coats in order to achieve an even finish.


Applying Rust-Oleum on a truck bed requires careful preparation work before beginning any painting. Start by cleaning the surface thoroughly with a brush or vacuum cleaner followed by using a degreaser and pressure washer for deeper cleaning needs. Next comes sanding down any areas with rust spots followed by two coats of primer for an even base coat before finally applying Rust-Oleum directly onto it with either a roller or brush in thin layers until desired coverage is achieved.
